The host−guest system of anisole incorporated into a cyclohexane matrix was investigated in a series ofhole-burning experiments. This system is unusual in that cyclohexane can freeze into coexisting solid phases.The hole-burning experiments support the existence of two crystalline phases and one disordered phase. Asecond surprising characteristic of this system is that the quasi-line absorption features of the spectra appearinverted at low temperature because of unexpected dominance of fluorescence and phosphorescence.
